My void found some plastic on the ground and ate it Saturday morning. It sounded fairly large as it took him awhile to swallow it. Granted I was trying to get to him to get it and he was running away so I am sure that slowed down the process. Saturday night he ate very little wet food. Sunday he threw up twice that I saw (we have three cats so hard to know if any other throw-up was his). It was kibble and mostly undigested. He ate more wet food Sunday night than Saturday, but not his usual amount. He is drinking and playing and being his usual self. I am going to call his vet today once they open. My question is how long does it normally take for a cat to pass an object? Thanks!
